Problems solved by technology
Although this method can shorten the cooling time of the electric pressure cooker, when the pressure limiting valve is opened, a large amount of soup will be discharged from the steam when the pressure limiting valve is discharged, which is neither safe nor hygienic.

Embodiment Construction
[0016] Further details will be given below in conjunction with the embodiments shown in the accompanying drawings.
[0017] The invention relates to a quick pressure relief method for an electric pressure cooker, based on an electric pressure cooker including a pot cover, a shell, a pot body, a sealing ring and an electrical part, especially:
[0018] A cavity is left between the inner and outer covers of the pot cover for cooling water distribution; water injection holes are set on the outer cover of the pot cover to communicate with the cavity; Ring-shaped water tank, when the pot cover is covered, the bottom of the cavity is facing the water tank, and there is a drain pipe extending downward at the bottom of the water tank; a drainage box is arranged under the drain pipe; all water injection, flowing water and drainage parts They are all electrically insulated from the electrical part; when rapid pressure relief is required, inject cold water from the water injection port, ...

The invention relates to a method for quickly relieving the pressure of an electric pressure cooking saucepan. In particular, an empty cavity is reserved and arranged between the internal cover and the external cover of a saucepan so as to be provided for the arrangement and flow of the cooing water and a water injection hole is arranged on the external cover of the saucepan cover, thus resulting in that the external cover is communicated with the empty cavity; a ring-shaped water groove is arranged at the top of a casing; when the saucepan cover is closed, the bottom of the empty cavity faces correctly to the water groove and a drainage pipe is extended downwards at the bottom of the water groove; all water injection, water flowing and drainage parts are separated from an electrical part through the electrical insulation; when the pressure needs to be quickly relieved, the cold water is injected from the water injection hole and the saucepan cover can be opened when the pressure in the saucepan is lowered to the atmospheric pressure. The saucepan cover (1) of an electric pressure cooking saucepan with quick pressure relief comprises a water cavity (13) formed by a gap between the external cover (11) and the internal cover (12). The method for quickly relieving the pressure of the electric pressure cooking saucepan can effectively solve the problem that the electric pressure cooking saucepan is too slowly depressurized and the electric pressure cooking saucepan with quick pressure relief realizes the method for quick pressure relief, thus assuring the safe and sanitary use of the electric pressure cooking saucepan with quick pressure relief.
Description
technical field [0001] The present invention relates to a kitchen cooking appliance, in particular to a pressure cooker and its closing device. Background technique [0002] Electric pressure cookers have developed rapidly in recent years due to saving electricity and time. The electric pressure cooker of the prior art comprises a pot cover, a pot body, a sealing ring, a shell and an electrical part. The electrical part includes a heating element and a control component. The pot cover is combined with the pot body to form a sealed cavity, and the bottom of the pot body is heated by a heating element, so that the temperature and pressure in the sealed cavity are higher than those of ordinary pressure cookers, thereby shortening the cooking time of food and saving energy. But there is a certain danger in opening the pot cover after cooking. If the pressure in the pot is greater than one atmospheric pressure, an explosion accident will occur if you are eager to open the cover...
